Course Description


This GLOMACS TAMCO High Voltage Switchgears training seminar focuses mainly on the installation, operation and maintenance of high voltage switchgear and equipment, regarding auxiliary equipment necessary for its operation. High voltage equipment plays a vital role in the safe distribution of electrical power.

The equipment needs to be operated in a safe manner securing continuity of supply to consumers. Technical aspects of switching devices, as well as their maintenance requirements, are briefly included in this training seminar to understand the risks associated with switchgear operation. Aspects of modern maintenance techniques in asset management will be covered at the level appropriate for this training course.

Protection systems are installed to prevent faults from damaging electrical plant and to initiate isolation of faulted sections in order to maintain continuity of supply elsewhere on the system.

This GLOMACS training seminar will highlight:

  • The roles of MV and HV switchgears
  • Compression principles of circuit breakers
  • Application and installation of vacuum interrupters
  • Importance of maintenance and testing
  • Protective relays and characteristics


At the end of this GLOMACS training course, you will learn to:

  • Understand the operations and types of TAMCO high voltage switchgears
  • Develop management and implementation of safe work systems
  • Design coordination of maintenance activities and maintaining system safety
  • Apply air and gas-insulated switchgear operations and maintenance
  • Explain the various types of protective relays
  • Analyse troubleshooting and repair of high voltage switchgears

Training Methodology

In this GLOMACS Electrical Engineering training course, the goals of each participant are discussed to ensure their needs are fulfilled, as far as possible. Questions are encouraged throughout, particularly at the daily wrap up sessions. Each participant will receive a copy of the comprehensive seminar notes. The presenter will outline and discuss the topics using computer displays, video clips and PowerPoint presentation. This training course is designed to have an interactive format to maximize delegate participation.

Organisational Impact

Upon completion of this GLOMACS training seminar, the organisational impact would be:

  • Technical training and up-skilling to improve and realise the full potential of a competent workforce
  • Productivity increase through minimisation of project time acceptance/design and commissioning
  • Identification for opportunities of improvements due to deep understanding of the presented state-of-the-art maintenance technologies
  • Networking of personnel with technology leaders and other engineers and technicians with substantial field experience
  • Exposure of personnel to the standard international procedures
  • Attitude change of workforce, as continuous follow up of new technologies

Personal Impact

On successful completion of this GLOMACS training seminar, delegate will be able to understand:

  • The TAMCO high voltage switchgears types, installation, operations and maintenance
  • The need for a routine inspection, adequate maintenance of equipment and accurate record keeping
  • Methods of maintenance management, using safe systems of work
  • How to coordinate maintenance activities for best utilisation of time and resources, while ensuring safety is not compromised
  • Switchgear maintenance requirements and techniques - properties of insulating oils and their analysis
  • The use of non-intrusive condition monitoring methods


The technicians and maintenance staff will be able to comprehend the types, construction, operations, the function of transformers. This will enable them to carry out effective maintenance activities.

This GLOMACS training programme is suitable for a wide range of professionals but will greatly benefit:

  • Electrical Engineers
  • Maintenance Technicians
  • Electrical Supervisors
  • Engineering Professionals
  • Managers of the electrical engineering department
